Title: Vertical die casting machine
Inventor: UENO TOYOAKI
IPC: B22D17/20
Filed: 1987-02-27
Granted: 1991-03-12
Abstract: VERTICAL DIE CASTING MACHINE             ABSTRACT OF THE DISCLOSURE    A vertical die casting machine of a vertically clamping type provided with a hydraulic piston-cylinder to actuate movable parting plates disposed between an injection sleeve and a stationary mold for constricting a melt passage including a runner hole formed in the stationary mold and a hollow end portion of the sleeve by an axial through-hole formed by the parting plates in a clamped state.  The parting plates enable to prevent a semi-solidified part of the melt "shell" formed in the sleeve before an injection operation from intruding into a mold cavity with the other hot melt part.     With a narrow runner hole having a diameter smaller than that of the sleeve, the parting plates are actuated to move in a clamped state in a direction to thereby shear a cold melt runner so that a molded product is allowed to move upward from the stationary mold with the runner separated from a cold melt bisket formed in the sleeve, but integral with the product.     With an enlarged runner hole having a diameter not less than that of the sleeve, the parting plates are actuated to separate from each other to thereby allow the bisket integral with the runner to move upward from the stationary mold through the enlarged runner hole with the mold product integral with the runner.

Title: Electric light bath
Inventor: WOLFF FRIEDRICH
IPC: A61N5/08
Filed: 1987-03-16
Granted: 1992-03-03
Abstract: ABSTRACT         The electric light bath consists of an infrared light source (S), which is preferably fitted with rod-like infrared radiators (IRR).  A first parabolically shaped reflector (R1) has the effect of an approximately vertical irradiation of the side of the body turned to-ward the infrared light source (S).  Futher reflectors (R2, R3) provide for as even an irradiation as possible from the side.        This arrangement ensures that at least 50%, but at most 90% of the body surface of the user is irradiated. In order that the radiation intensity is strong enough for perspiration to being but not for an unpleasant heat sen-sation to occur, a controller which can be operated by the user is preferably provided.        An IR-B and an IR-C filter keeps back that part of the IR radiation which would cause a heating up of the interior body temperature.  A further filter keeps back the visible range of the radiation spectrum to the extent that only light orange light is visible.        The IR radiation can be readily supplemented with UV radiation.     (Figure 1)
